In Great Britain May 26, 1950 3 Claims. (01.164-65) This inventionrelates to machines for cuttin strips from tubular textile fabrics.

Strips of textile fabric cut in such fashion that the two edges arerelatively extensible are required in certain textile garmentmanufacturing processes, e. g. in the neck binding of knitted jumpers,sweaters, vests and the like.

' A machine has been proposed for producing said strip from tubularfabric comprising one or more power-driven knives into contact withwhich the fabric is guided continuously by an operator so as to cut afinite length of tubular fabric in helical fashion into a continuousstrip or strips.

Output from such a machine is necessarily limited ,by the skill andcapability of the operatorand practice at least three vstrips areusually cut simultaneously in order that the output may be tolerablyeconomic. If a length of helically cut strip knitted fabric is laid on aflat surface, it will be seen that the lateral rows of stitches do notlie truly at right angles to the edges of the strip, and if such stripis then curved while still remaining flat upon said surface, the lateralrows of stitches will be found to be decreasingly inclined to the edgesof the strip from one end of the strip to the other, thus involving alack of symmetry. Whilst this lack of symmetry is slight in the case ofnarrow strips, it becomes substantial in the case of wide strips, such,for example, as is involved when two or more strips are simultaneouslycut, as in the machine referred to above.

The object of the present invention is to provide a machine which willautomatically and economically cut strips of textile fabric from a tubethereof with a minimum of non-symmetry referred to above.

The invention consists in an automatic machine for cutting tubulartextile fabric into a helical strip comprising means for supporting anend of the fabric tube, means for feeding the fabric tube axially inrelation to said fabric supporting means, a power driven knife and afinger member, said knife and finger member being adapted partially toproject into a circumferential groove or slot in said fabric supportingmeans, and power means for rotating said fabric supporting meansrelatively to said knife and finger.

The invention also consists in an automatic machine as set forth in thepreceding paragraph, wherein said feeding means comprise a carding pador pads on said fabric supporting means and a plurality of reciprocatingarms carrying carding pads adapted to co-operate with said former pad orpads.

The invention also consists in an automatic machine as set forth in thepreceding paragraph including also one or more rotary brushes adapted toengage the fabric in the vicinity of the said finger member.

The invention also consists in an automatic machine as set forth in anyof the three preceding paragraphs wherein the fabric supporting means isstationary.

The invention also'consists' in, an automatic machine as set forth inany of the four preceding paragraphs, wherein a drum is provided whichis urged into contact With the, cut strip orfabric and is adapted toreceive and coil the cut strip thereon.

The invention also consists in an automatic machine as set forth in thepreceding paragraph including mechanism adapted to stop the machine whenthe drum is loaded to a predetermined depth.

The invention also consists in machines for automatically cuttingtubular textile fabric into a helical strip or strips'substantially ashereinafter described with reference to the accompanying drawings.

Referring to the accompanying diagrammatic drawings: I

Figure 1 is a side elevational View of one con venient construction ofmachine embodying the present invention,

Figure 2 is a plan view thereof with parts broken away,

Figure 3 is a half vertical sectional view on the line IIIIII of Figure2,

Figures 4 and 5 are enlarged sectional views of details. In carrying theinvention into effect accordmg to one form illustrated by way of examplein the accompanying drawings, a fixed vertical pillar a is providedcarrying at its upper end a cylindrical head b furnished with a conicaltop 0. Surrounding the pillar and adapted to rotate on ball bearings 01thereon is a series of arms e upon which are mounted a plurality ofvertical columns ,f, a ring 3, a finger member g, an electricmotordriven rotary knife h, a rotary brush 2 and a spring-urged arm 7for carrying a winding drum is.

The table structure comprising the arms e, pillars f and ring 3, isadapted to be driven by gearing m n from a fixed motor 4. A fixedbracket member 0 carries a ring p to which a pluralits of arms q arepivoted at 1', these arms rigidly carrying depending arms 8 andspring-urged pivoted arms t. The lower ends of the latter arms The lowerends of the arms s are engagedby a series of cams a: supported on therotary table 6.

The brush 2' is adapted to be rotated by epicyclic gearing z from afixed toothed ring y encircling the pillar a. i

The cams .r are furnished with screws 2 for adjustment whereby thestroke of the oscillating arms t may be varied to vary the amount oftextile material that is fed downwards for each downward stroke of thearms; the width of the cut textile strip may thus be varied at will.

The cut material is laid around the spring-, loaded drum It so that thestrip as it is cut is Wound on to the drum.

Convenient mechanism is provided to stop the machine when the driun hasbecome loaded to a desired diameter.

In operation, one end of a tube of textile material is introduced overthe conical end c of the head I) and as the machine operates the loweredge of the tube is fed downwards by the moving carding pads u so thatit passes over and beyond the groove or slot 11 in the head. Rotation ofthe finger g which projects partially into the aforesaid slot inconjunction with the rotary brush 1' assists the passage of the loweredge of the textile tube downwards over the slot. The rotating rotaryknife It cuts the strip to the predetermined width and the strip isloaded on the drum 7c.

In the above construction of the machine, the

textile tube moves longitudinally as it is fed to the machine but doesnot rotate, but if desired the textile tube, feedin arms and feedinghead may be caused to rotate whilst the knife or knives, finger, brushand cams for reciprocating the feedling arms, etc. may be stationary.

I claim:

1. In an automatic machine for cutting tubular textile fabric into ahelical strip, cylindrical means for supporting an end of the fabrictube, means for feeding the fabric tube axially in relation to saidfabric supporting means including a plurality of feeding fingersdisposed in close juxtaposition around the periphery of said supportingmeans, a power driven knife and a guide finger member, said knife andguide finger member being adapted partially to project into acircumferential groove or slot in said fabric supporting means, andpower means for rotating said fabric supportin means relatively to saidknife and guide finger.

2. An automatic machine as claimed in claim 1, wherein said feedingfingers comprise reciprocating arms carrying carding pads adapted toco-operate with at least one carding pad on said fabric supportingmeans.

3. An automatic machine as claimed in claim 1 wherein the fabricsupporting means is stationary.

INGO PASOLD.
